Dependence oftheair consumption and thepositionofthe body on theselectedmethodofdivingkick and swimming speed
Ehl, Sebastian ; Vondrášek, David (advisor) ; Bačáková, Radka (referee)
Title: Dependence of the air consumption and the position of the body on the selected method of diving kick and swimming speed Objectives: The goal of this work is to find out the relationship between the diver's swimming speed and the air consumption while using two different methods of diving kicks - flutter and frog kick. At the same time, assess the dependence of the position of the body and head on the swimming speed and method of diving kicks. Methods: In this work was used method of collecting data in real conditions by measuring devices and statistical evaluation of collected data. Results: The results are presented by graphs both in the text of this work and in attachment for its large size. The results of all probands are presented in summary graphs and for selected values the degree of association is calculated in tables using the Pearson correlation coefficient. The main result is the confirmation of the reduction of the deviation from the horizontal position when comparing the slow and higher swimming speeds of both flutter and frog kick. The most effective way for a diver to overcome 50 meters below the water surface was determined to be a flutter kick at medium speed (average 0,37 m/s). Keywords: scuba diving, body position, head position, air consumption, speed of swimming, flutter...

Blažek, Dušan ; Fiala, Miloš (advisor) ; Bažant, Filip (referee)
Title: Impact of stress situations on heart rate and air consumption under water Objectives: The aim of this labour is to determine relation between air consumption in our selected stress situation. Determinte strongest stress situation from our selection on the base of increase of stress indicators (hpb, minute air consumption). Next aim is to determine context between stress situation at beginning diver, their heart rate and air consumption. Last but not least aim of this labour is to conduce to optimal method and reccomendation related to safety and psychological resistance of the diver. Methods: In our thesis we used a method of analysis and a method of comparison. We apllied the method of analysis in each individual measurement and the method of comparison in part comparing each measurement together. Results: By measurements was found out, that air consumption is at different stress situations under watter dissimilar. There is also very wild diference between air consumption and heart rate at each specimen.. Like optimal method of psychological resistance of the diver was selected method of combination. Significant stress, was dive itself. The combination consists of training concrete situation and method of general stress handling. Keywords: scuba diving, heart rate, air consumption, stress

Differences in inhalation between men and famales during the identic scuba diving output
Rosenkranzová, Michaela ; Bažant, Filip (advisor) ; Vondrášek, David (referee)
Name: : The difference of consumption of a medium being inhaled between a man and a woman at the same level of endurance in scuba diving. Goals: The primary goal of this work, is to determine if and how is the amount of the inhaled medium depending on the gender of the divers. Compare the consumption between men and women while being faced with the same amount of stress, meaning during a united profile of a dive, try to maximize the decrease of the influence of stress factors. Confirm or deny the hypothesis that men show higher values of the inhaled medium. Methods: The theoretical part of this paper, was created based on the research of the appropriate literature. To obtain all the data, there was used the method of experiments, the results were then analyzed, compared and than statistically evaluated using the Students T- test. Probandi (n=10+10) took part in a 30 minute long and 20 meters deep dive in Bořená hora, during which their consumption of the inhaled medium was recorded every 5 seconds using a special underwater computer with a probe. Results: It was found out that men, during the same dive, consume more air than women because of their higher body weight. Key words: scuba diving, air, sex, respirator, minute ventilation
